I’m trying to add a custom LLM to Discourse AI plugin. When I press the ‘test’ button I get “Internal Server Error”. Is there a way of debugging this or getting a better error message? When I go into the docker image and curl the /v1/models, I’m able to fetch this correctly. The model name is “mod…

Trying another one gives: Trying to contact the model returned this error: {"error":{"code":404,"message":"File Not Found","type":"not_found_error"}} But it doesn’t display what URL/model it is trying to fetch which might help to debug.

What inference server are you using? vLLM? When configuring the URL, add the path /v1/chat/completions at the end.

[image] Falco: What is the error you see on /logs ? Ah. I didn’t know about /logs! NameError (undefined local variable or method 'tokenizer' for an instance of DiscourseAi::Completions::Dialects::ChatGpt) app/controllers/application_controller.rb:424:in 'block in with_resolved_local Hmm. Th…

Anyone managed to get DeepSeek API working? I’m trying to figure out the right incantation to get it to work with Discourse. I have it working in Open WebUI and other clients.

There’s a topic here about it [image] Can I add other LLM? support It works with VLLM, you can can just configure a VLLM endpoint and it should work out of the box.
